Weston Stainless, a leading manufacturer in Midland, UK, is a well-established manufacturer of premium stainless steel products, providing reliable and corrosion-resistant solutions to a number of industries. Their Stainless Steel 347H Bars are constructed using a high-carbon variant of columbium-stabilized austenitic stainless steel, providing improved strength and increased resistance to intergranular corrosion. These bars are supplied in a variety of shapes, such as round, square, flat, and hex bars, and thus suit structural and machining purposes. Due to good mechanical properties, high-temperature stability, and weldability, SS 347H bars are ideal for challenging environments that demand durability, strength, and long service life.
Stainless Steel 347H Bars have 17-19% chromium, 9-13% nickel, and columbium (niobium), which increases their stability against carbide precipitation at high temperatures. The increased carbon content enhances their strength at high temperatures. They possess a tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40%. Their hardness is around 95 HRB. The physical characteristics are a density of 7.9 g/cm³, melting point of 1400°C, and thermal conductivity of 16.3 W/m-K, providing strength and long service life under harsh conditions.
